+VIM LICENSE
+
+I) There are no restrictions on distributing unmodified copies of Vim except
+that they must include this license text. You can also distribute unmodified
+parts of Vim , likewise unrestricted except that they must include this license
+text. You are also allowed to include executables that you made from the unmodified
+Vim sources, plus your own usage examples and Vim scripts.
+
+II) It is allowed to distribute a modified (or extended) version of Vim ,
+including executables and/or source code, when the following four conditions
+are met:
+
+      1) This license text must be included unmodified.
+
+2) The modified Vim must be distributed in one of the following five ways:
+
+a) If you make changes to Vim yourself, you must clearly describe in the distribution
+how to contact you. When the maintainer asks you (in any way) for a copy of
+the modified Vim you distributed, you must make your changes, including source
+code, available to the maintainer without fee. The maintainer reserves the
+right to include your changes in the official version of Vim . What the maintainer
+will do with your changes and under what license they will be distributed
+is negotiable. If there has been no negotiation then this license, or a later
+version, also applies to your changes. The current maintainer is Bram Moolenaar
+<Bram@vim.org>. If this changes it will be announced in appropriate places
+(most likely vim.sf.net, www.vim.org and/or comp.editors). When it is completely
+impossible to contact the maintainer, the obligation to send him your changes
+ceases. Once the maintainer has confirmed that he has received your changes
+they will not have to be sent again.
+
+b) If you have received a modified Vim that was distributed as mentioned under
+a) you are allowed to further distribute it unmodified, as mentioned at I).
+If you make additional changes the text under a) applies to those changes.
+
+c) Provide all the changes, including source code, with every copy of the
+modified Vim you distribute. This may be done in the form of a context diff.
+You can choose what license to use for new code you add. The changes and their
+license must not restrict others from making their own changes to the official
+version of Vim .
+
+d) When you have a modified Vim which includes changes as mentioned under
+c), you can distribute it without the source code for the changes if the following
+three conditions are met:
+
+- The license that applies to the changes permits you to distribute the changes
+to the Vim maintainer without fee or restriction, and permits the Vim maintainer
+to include the changes in the official version of Vim without fee or restriction.
+
+- You keep the changes for at least three years after last distributing the
+corresponding modified Vim . When the maintainer or someone who you distributed
+the modified Vim to asks you (in any way) for the changes within this period,
+you must make them available to him.
+
+- You clearly describe in the distribution how to contact you. This contact
+information must remain valid for at least three years after last distributing
+the corresponding modified Vim , or as long as possible.
+
+e) When the GNU General Public License (GPL) applies to the changes, you can
+distribute the modified Vim under the GNU GPL version 2 or any later version.
+
+3) A message must be added, at least in the output of the ":version" command
+and in the intro screen, such that the user of the modified Vim is able to
+see that it was modified. When distributing as mentioned under 2)e) adding
+the message is only required for as far as this does not conflict with the
+license used for the changes.
+
+4) The contact information as required under 2)a) and 2)d) must not be removed
+or changed, except that the person himself can make corrections.
+
+III) If you distribute a modified version of Vim , you are encouraged to use
+the Vim license for your changes and make them available to the maintainer,
+including the source code. The preferred way to do this is by e-mail or by
+uploading the files to a server and e-mailing the URL. If the number of changes
+is small (e.g., a modified Makefile) e-mailing a context diff will do. The
+e-mail address to be used is <maintainer@vim.org>
+
+IV) It is not allowed to remove this license from the distribution of the
+Vim sources, parts of it or from a modified version. You may use this license
+for previous Vim releases instead of the license that they came with, at your
+option.
